In the very heart of Auvergne enjoy a unique timeless experience with an enriching guided tour lasting about 45 minutes.

After a jaunt across an underground universe made of water and stone you will discover the hot springs’ strange power as you follow their courses to the Atelier, a sanctuary where the secrets of a rare handicraft have been preserved for over 2 centuries. The Petrifying Ladder with its 14-meter-high waterfall will unveil human genius as to the artistic use of calcium carbonate.

To conclude your visit brilliantly, as a connoisseur you will appreciate our artworks resulting from nature’s riches combined with human manual intelligence.

A special rate of 5,50 €/pers is granted to groups (of at least 20 paying adults) who book in advance, free for their leader and coach driver.

It is possible to obtain a guided tour in English or German only on pre-booking. Contact the manager at
